Cover for vitreous vessels



$ 1932. T. w. BEATTY COVER FOR VITREOUS VESSELS Filed June 25, 1929 fig-WV %VENTOR one hand.

Patented Feb. 3, 1932 UNITED STTES PATET 'F ic THOMAS W. BEATTY, OF COLUMBIANA, OHIO, ASSIGNOR T0 PORCEL-IER MANUFACTUR- INGr COMPANY, OF EAST LIVERPOOL, OHIO, A CORPORATION OF PENNSYLVANIA COVER FOR VITREOUS VESSELS This invention relates to vitreous, ceramic or earthenware vessels, particularly vessels of the nature of coffee percolators, tea-pots and similar articles of household use.

In a copending application in the name of Jacob Dym, Serial No. 317,944, filed November 8, 1928, there is disclosed a coifee percolator formed entirely of porcelain. Considerable difficulty has been encountered in providing a porcelain top for such a percolator due to the factthat there can be no hinged connection between the top and the body of the percolator. Likewise in the ordinary teapot made of earthenware or glass, the top must be entirely separate from the body of the teapot, and in pouringfrom such a teapot it is necessary to hold the co er in place with Consequently, in ordinary earthenware teapots it is quite frequently the practice to provide a wide flange on the cover wh ch projects well down into the teapot.

According to the present invention there is provided aceramic or vitreous cover for vitreous vessels of this nature having means thereon for frictionally or yieldably holding the cover in place in the vessel so that it will remain in place, even when the vessel is entirely inverted and notwithstanding the relatively heavy weight of the cover. This holding means preferably does not require any modification in the construction of the body of the vessel, and it can be cheaply constructed and conveniently used. The invention may be readily understood'by reference to the accompanying drawings which illustrate certain preferred embodiments of my invention.

In the drawings 7 Figure 1 is a side elevation of a vessel and cover embodying the present invention, a part of the vessel being broken away to show the relation between the cover and the vessel;

Figure 2 is a bottom plan view of the cover;

In the drawings, 2 designates a non-me- 1929. Serial No. 373,521.

tallic vessel of a frangible material, such as porcelain, glass or china. This vessel may be of any suitable shape and may be designed for any purpose, although it is shown as. being applied to a coffee percolator. At the top of the vessel 2 is the usual neck 3. The cover t has a laterally extending flange 5 adapted to seat on the neck 3 in the usual manner and has a depending flange 6 adapted to project down into the neck, the flange 6 being of slightly less diameter than the 1nsidc diameter of the neck.

In the flange 6 at diametrically opposite points are recesses or notches 7, and in the flange 6 at 8 is a smaller recess or notch. In the construction shown in Figures 2 and 3 there is an annular recess 9 around the top of the flange 6 just under the horizontal flange 5. Received in this'annular groove is a wire 10 of spring metal, this metal being made of stainless steel or other metal which will not be corroded by the contents of the vessel. The wire 10 has vertically depending loops 11 formed therein at diametrically opposite points, these loops being positioned adjacent the recesses 7. i

The lowerendsof the loops are inwardly turned, as indicated at 11a, to facilitate the insertion of the cover into the vessel. The ends of the wire 9 are turned in, and'are received in the recess 8, as clearly shown in Figure 2. T hese inwardly turned ends of the wire serve to prevent the wire from rotating on the cover;

The loops 11 in the wire provide spring fingers which can yieldinwardly when the cover is forced into the neck of the vessel. However, when the cover is forced inwardly, these fingers press out against the inside of the neck and thereby frictionally hold the cover in the neck. If the neck isprovided with an inwardly turned flange, as is common in teapots, the high point 116 of these fingers will project under the flange and thus form an interlocking engagement between the cover and thevessel. Te remove the cover, it need merely be lifted off. The spring fingers will yield sufiicientlyto permit the cover to be removed even where the vessel is one having a flange in the neck thereof. In Figure cover 15 has a shoulder 16 on the under side thereof and a depending flange 17 similar to the flange 6 of the construction shown in Figures 2 and 3. At two or more points on the flange 17 are shallow recesses in which are set metal plates 18. These metal plates are secured in place by bolts 19 passing through the flanges l7 and having nuts 20 on the inner ends thereof. Each of the plates 18 has an outwardly struck spring portion 21 adapted to engage the inside of the neck of the vessel to which the cover is applied. The spring fingers 21 are shaped to permit of the easy insertion of the cover into the vessel.

In the construction shown in both Figures 2 and 4 the cover has a central opening 22 adapted to receive the usual glass percolator top, but it will be understood that the invention is not confined to a cover for apercolator.

The terms vitreous and frangible as herein used and as used in the claims, shall be understood to include any non-metallic vessel of porcelain. china, glass or earthenware.

lVhile I have shown certain preferred embodiments of my invention, it will be understood that this is merely by way of illustration, and that the invention may be otherwise embodied within the scope and contemplation of the appended claims.

I claim:

1. A non-metallic frangible cover for vessels comprising a cover member having a depending flange thereon adapted to project into the neck of the vessel to which the cover is applied, said flange having notches therein, and means located opposite the notches and carried by the cover on the outside of the flange for yieldably engaging the interior of the neck of the vesselto which the cover is applied. 7

2. A cover for vessels comprising a nonmetallic frangible body having a shoulder thereon and having a flange projecting downwardly below the shoulder, said flange being adapted to project into the neck of av vessel to which the cover is applied, said flange having an annular recess therein beneath the shoulder, said recess being on the outside of the flange, a wire in said recess, said wire having looped portions forming vertically extending yieldable fingers adapted to engage the interior of the neck of a vessel to which the cover is applied for holding the cover in place on the vessel.

3. A cover for vessels comprising a nonmetallic frangible body having a shoulder thereon and having a flange projecting downwardly below the shoulder, said flange being adapted to project into the neck of a vessel to which the cover is applied, said flange having an annular recess therein beneath the shoulder and formed in the outside of the flange, a wire in said recess, said wire having looped portions forming vertically extending yieldable fingers adapted to engage the interior of the neck of a vessel to which the cover is applied for holding the cover in place on the vessel, said flange having notches therein into which the looped portions of the wire may yield when the cover is applied to the vessel to which it is adapted.

a. A cover for vessels comprising a nonmetallic frangible body having a shoulder thereon and having a flange projecting downwardly below the shoulder, said flange being adapted to project into the neck of a vessel to which the cover is applied, said flange having an'annular recess therein, beneath the shoulder, the recess being on the outside of the flange, a wire in said recess, said wire having looped portions forming vertically extending yieldable fingers adapted to engage the interior of the neck of a vessel to which the cover is applied for holding the cover in place on the vessel, said flange having notches therein into which the looped portions of the wire may yield when the cover is applied to the vessel to which it is adapted,

the ends of said wire being received in an-.

other notch in the flange, the ends being turned inwardly, thereby holding the wire against rotation on the cover.

In testimony whereof I have hereunto set my hand. T

THOMAS l V. BEATTY.
